    Application is 32 bit or 64 bit

    Hi,

    How to check ( command for it) an application installed in Ubuntu 12.04 is 32 bit application or 64 bit application. I need to check PostgreSQL which is already got installed there in Ubuntu 12.04. Please provide Linux command to check whether this PostgreSQL is 32 bit or 64 bit.

    apt-cache will show you package information. Then pipe it to grep to get the Arch.
    Code:
    sudo apt-cache show postgresql | grep Architecture

    Do you need to sudo to run apt-cache?

    No just a habit of my apt skills to add sudo.

    You can run 'file' against the binary to see what it is. For example

    Code:
    sander@flappie:~$ file /usr/lib/chromium-browser/chromium-browser
    /usr/lib/chromium-browser/chromium-browser: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x47a4b12a46cb7121f88413d51598f58b568cd042, stripped
    sander@flappie:~$
    So my chromium-browser is ... 64-bit
